1. Legend:
Demagnetization (D) event
At the end of the demagnetization phase, current no longer goes through the free-wheeling
diodes. The voltage on the non-excited winding terminal goes from one of the power rail
voltages to the common star connection voltage plus the BEMF voltage. In some cases (if
the BEMF voltage is positive and the free-wheeling diodes are at ground for example) this
end of demagnetization can be seen as a voltage edge on the selected MCIx input and it is
called a hardware demagnetization event D
The D event filter can be used to select the number of consecutive D events needed to
generate the D
If enabled by the HDM bit in the MCRB register, the current value of the MTIM timer is
captured in register MDREG when this event occurs in order to be able to simulate the
demagnetization phase for the next steps.
